njsmoker83 0 Posted July 17, 2013 I have to run wires from an attic to a basement in a two story house. I have been reading you can run THROUGH the HVAC return. Is that true? Share this post Link to post Share on other sites
RandyParlee 0 Posted July 17, 2013 Sure, just get the plenum rated stuff. There may also be room to run down next to the plumbing stack. Good luck! Share this post Link to post Share on other sites
SectorSecurity 0 Posted July 18, 2013 Seen it done many times, and with the right cable it is not a problem. You have to remember if you have cabling in your HVAC and you have a fire there is potential for noxious gases to spread through your home, thus the need for plenum rated cable. I do suggest trying next to the HVAC or plumbing stack, often you can get up or down these locations with push sticks. Don't know when your place was built but in newer places I know they have started adding what we call future pipes, basically opening from the basement to second floor. Look around your basement for open holes. Share this post Link to post Share on other sites
